The reduced power PDCCH listening period may include one of:

1) The PDCCH skips the period indicated by the indication.

2) During DRX. The DRX period includes a DRX activation time (duration) and/or a DRX sleep time (opportunity for DRX). In this embodiment, the terminal may monitor the LP-WUS first and not the PDCCH during the DRX activation period, and monitor the PDCCH when the LP-WUS wakes up, and since the power consumption for monitoring the LP-WUS will be far less than the power consumption for monitoring the PDCCH, the terminal power consumption may be further reduced; in this embodiment, the terminal may also monitor the LP-WUS during the DRX sleep period, so as to wake up the terminal through the LP-WUS in time, that is, without waiting for the next DRX activation period, which is beneficial to reduce the data transmission delay.

Specifically, for example, the unit of PDCCH skip time is a slot (slot), and the PDCCH skip indication includes a bitmap (bitmap), for example, 10 bits, each bit corresponds to one slot, the slot corresponding to the bit value (bit) 1 needs to monitor LP-WUS, and the slot corresponding to the bit value 0 does not need to monitor LP-WUS.

2) Third information indicating a search space set group switch (Search Space Set Group switching, SSSG) listening period, the start time of the LP-WUS being related to the SSSG listening period.

For example, the listening start time of the LP-WUS signal differs from the SSSG listening period (may be the start time of the SSSG listening period) by a fixed time interval T1, T1 being equal to or greater than 0, specifically, for example, the interval T1 after the start time of the SSSG listening period is the listening start time of the LP-WUS.

To describe in detail the method of interception and transmission of LP-WUS provided in the embodiments of the present application, several specific embodiments will be described below.

Example 1

The embodiment terminal receives the LP-WUS in the RRC connected state. The active time listening to LP-WUS occurs during PDCCH skipping.

As shown in fig. 3, the transmission time of LP-WUS may exist inside and outside the PDCCH skip period, in which the terminal skips monitoring (i.e., does not monitor) the LP-WUS outside the PDCCH skip period, and the terminal listens to the LP-WUS in the PDCCH skip period, i.e., the black padding is the inactive LP-WUS in fig. 3, and the diagonal padding is the active LP-WUS.

In addition, as shown in fig. 4, the transmission time of the LP-WUS may exist in the DRX active period and the DRX sleep period. In this embodiment, the terminal may monitor the LP-WUS first and not the PDCCH during the DRX activation period, and monitor the PDCCH when the LP-WUS wakes up, and since the power consumption for monitoring the LP-WUS will be far less than the power consumption for monitoring the PDCCH, the terminal power consumption may be further reduced; in this embodiment, the terminal may also monitor the LP-WUS during the DRX sleep period, so as to wake up the terminal through the LP-WUS in time, that is, without waiting for the next DRX activation period, which is beneficial to reduce the data transmission delay.

In another embodiment, the terminal receives the LP-WUS in the RRC connected state. The active moments of listening to the LP-WUS occur at different SSSGs. The terminal listens to the LP-WUS for the listening period of the sparse SSSG and may not listen to the LP-WUS for the listening period of the dense SSSG. In other embodiments, the terminal listens to the LP-WUS for the listening period of the sparse SSSG and also to the LP-WUS for the listening period of the dense SSSG.

As shown in fig. 5, the period of the sparse SSSG is assumed to be 4 slots, wherein slots 1-12 are sparse SSSG, slots 13-15 are dense SSSG, the terminal listens to the LP-WUS on slots 1,2,3,5,6,7,9, 10, 11, and may not listen to the LP-WUS on slots 4,8, 12, 13, 14, 15.

Example two

And the terminal stops monitoring the PDCCH within a specified time length according to the received PDCCH skip instruction, and monitors the LP-WUS at a specific position during the PDCCH skip according to the association relation between the LP-WUS and the PDCCH skip instruction.

The embodiment can agree on the association relation through network configuration or protocol, for example, the period and the monitoring duration of the LP-WUS are respectively 1/N of the skipping time length of the PDCCH ₁ 、1/N ₂ Multiple, n1=4, n2=8.

And the terminal starts to monitor the LP-WUS when the 1 st, 3 rd, 5 th and 7 th ms of the PDCCH skipping period are ended, the period of the LP-WUS is 2ms, and the monitoring duration in the monitoring period is 1ms according to the PDCCH skipping instruction, wherein the length of the PDCCH skipping period is 8ms, as shown in fig. 6.

The association relation between the monitoring time of the LP-WUS monitoring and the DRX configuration information is the same, as shown in fig. 7, the terminal can monitor the LP-WUS first during the DRX activation period without monitoring the PDCCH, and monitor the PDCCH when the LP-WUS wakes up, and the power consumption of monitoring the LP-WUS is far less than the power consumption of monitoring the PDCCH, so that the power consumption of the terminal can be further reduced; in this embodiment, the terminal may also monitor the LP-WUS during the DRX sleep period, so as to wake up the terminal through the LP-WUS in time, that is, without waiting for the next DRX activation period, which is beneficial to reduce the data transmission delay. In this embodiment, both times of listening to the LP-WUS are within a reduced power PDCCH listening period.

Example III

In this embodiment, the terminal receives a PDCCH skip indication in the RRC connected state, and the PDCCH skip indication simultaneously indicates the LP-WUS listening time, for example, the unit of PDCCH skip time is slot. The PDCCH skip indication comprises a bitmap, for example 10 bits, each bit corresponds to a slot, the slot corresponding to bit value (bit) 1 needs to monitor LP-WUS, and the slot corresponding to bit value 0 does not need to monitor LP-WUS.

As shown in fig. 8, the enhanced PDCCH skip indication is 10 slots, the bitmap is 10 bits, specifically 1010101010, and under the bitmap indication, the terminal listens to the LP-WUS at the 1 st, 3 rd, 5 th, 7 th and 9 th slots. If the terminal monitors the LP-WUS in a slot, the PDCCH skipping action is stopped immediately.

Example IV

In this embodiment, the first information includes a time offset indicated by DCI, where a starting reference point of the time offset includes a time domain position where the PDCCH skip indication is received, DRX configuration information (on duration), and after determining the starting reference point, for example, referring to a receiving time of the current PDCCH skip indication, according to the first time offset included in the first information, the system frame may start to monitor the LP-WUS at a corresponding position, and the time length is used to determine a monitoring duration of the LP-WUS.

For example, as shown in fig. 9, the network side device indicates, through the PDCCH skip indication, a period of time during which the PDCCH skips to monitor the LP-WUS, and the terminal starts to monitor the LP-WUS after receiving the first time offset after the PDCCH skip indication. For another example, the terminal starts listening to the LP-WUS after a second time offset after the start time of the DRX activation period. For another example, the terminal starts listening to the LP-WUS after a third time offset after SFN 1.

Example five

In this embodiment, the terminal receives a PDCCH skip indication, which simultaneously indicates the listening time of the LP-WUS, including a start time, a listening duration, etc. For example, as shown in fig. 10, the duration of the PDCCH skip period indicated by the PDCCH skip indication is 8ms, and the terminal only needs to start listening to the LP-WUS within the last 2ms, and the listening duration is 2ms.

The listening method of the LP-WUS according to an embodiment of the present application is described in detail above in connection with fig. 2. The transmission method of the LP-WUS according to an embodiment of the present application will be described in detail with reference to fig. 11.
